Galileo Standing Liquid Thermometer, Multicolor Floating Spheres Balls, Measures Temperatures from 60ºF to 82ºF,   (9.5 Inches) 

• This gorgeous Galileo thermometer is a work of art with blown glass balls of varying colors in a delicate blown glass cylinder
• The glass balls rise and fall within the liquid-filled cylinder to reflect changes in the temperature, and each ball has a small charm to read the temperature
• Attached to each bubble is a little metal tag that indicates a temperature. These metal tags are calibrated counterweights. The weight of each tag is slightly different from the others
• The Galileo thermometer consists of a sealed glass tube that is filled with liquid and several floating bubbles. The bubbles are glass spheres filled with a colored liquid mixture
• As the temperature of the air outside the thermometer changes, so does the temperature of the liquid surrounding the bubbles. As the temperature of the liquid changes, it either expands or contracts, thereby changing its density, 
• Comes in a nice box for protection, And ready for a gift for anyone you want to impress
